- the snowboard binding A of the present invention (first aspect) has a highback 4 in the rear part of a base section 3 that is rotatably and pivotably mounted in the longitudinal direction, and the highback 4 is locked in a state in which rearward rotation is impossible by a lock mechanism 6 while a boot 2 is worn.
- a lock lever 7 rotatably provided to the rear surface section of the highback 4 is rotatably operated, and when the lock lever 7 is extended along the rear surface section of the highback 4 , a connecting cord 8 provided so as to span between the lock lever 7 and the base section 3 is tensioned, the highback 4 is placed in a locked state in which rearward rotation is impossible, and the boot 2 placed on the base section 3 is bound to the base section 3 by the highback 4 and a strap 5 provided in a more front-side position of the base section 3 than the highback 4 (resulting in a state in which the boot 2 is worn.
- the lock mechanism 6 is unlocked and rotated so as to tilt the highback 4 rearward.
- the highback 4 when placed in an unlocked state, automatically rotates rearward by the rotatable urging of an urging body 9 provided to the highback 4 , and when the highback 4 automatically rotates rearward, and so that when the highback 4 arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, the connecting cord 8 is tensioned, the projecting orientation of the lock lever 7 from the highback 4 rear surface section is maintained, and the lock lever 7 in the projecting orientation makes contact with the snow surface S below the snowboard 1 to bring about a slide-preventing effect.
- the boot 2 When the highback 4 is rotated rearward, the boot 2 is allowed to move rearward in relation to the base section 3 , and the boot 2 is allowed to move to the rearward position unrestrained by the strap 5 , whereby the boot 2 can be removed from the base section 3 .
- the boot 2 can be mounted to or dismounted from the base section 3 without removing the strap 5 , and once the state of restraint of the boot by the strap 5 has been adjusted, the same state of restraint of the boot 2 can be created each usage without the process for adjustment each time the boot 2 is mounted/dismounted.
- the lock lever 7 can be separated from the snow surface S and the slide-preventing state released.
- a slide-preventing effect is demonstrated while the boot 2 is being removed from the binding A in similar fashion to a ski stopper, and it is therefore possible to prevent the snowboard 1 from sliding down the ski slope without a tether attachment, to prevent the snowboard 1 from sliding down the ski slope when the boots 2 are mounted or dismounted (when both feet are removed from the binding), and to prevent a snowboard 1 leaning up against a stand from accidentally falling down due to wind or other factor and then slide down the ski slope. It is thereby possible to avoid accidents in which an uncontrolled snowboard 1 collides with other skiers and snowboarders.

Abstract
Description
- The present invention relates to a snowboard binding and a stopper device for a snowboard binding in which a stopper (slide prevention) function of a snowboard works in cooperation with an operation for removing a boot.
- Japanese Patent No. 2832783 (Patent Document 1) is an example of a conventional snowboard binding.
- First Patent Document 1 shall be briefly described. The invention comprises a base plate, a highback in which the lower portion thereof is tiltably and pivotably mounted on the base plate, a strap section in which the lower end section thereof is attached to the portion that extends further downward than the pivotably mounted section of the highback, and unlockable locking means for locking the rearward tilt of the highback, the locking means being composed of a wire that extends along the back surface of the highback, the two ends of the wire being linked to both sides of the base plate portion further forward than the pivotably mounted section of the highback, and a lever that is rotatably and pivotably mounted on the highback and that is operated to switch the wire between a state of tension a state of non-tension.
- According to Patent Document 1, there are advantages in that the highback is tilted rearward by releasing the lock with a lever operation to allow a boot to be very readily detached from the baseboard without disengaging the ratchet and ratchet belt of the strap section, and the fastening arrangement of the boot can be the same each time.
- [Patent Document 1] Japanese Patent No. 2832783
- A slide-preventing band referred to as a tether which is wound around a leg is provided to a snowboard binding.
- However, the tether is bothersome in that the operation for mounting to/dismounting from a foot must be carried out separately from the operation for mounting/dismounting a boot to the binding, and since the appearance of the tether wound about a leg may be considered to be poor, the use of the tether has been inconsistent.
- Accordingly, there is a persistent problem of accidents that occur when an un-tethered snowboard slides down the ski slope and collides with other skiers and snowboarders, and since the stopper function does not automatically function when a boot is removed from the binding as does the stopper for a ski, the snowboard may slide down the ski slope when the boots are being mounted/dismounted (when both feet are removed from the binding), and a snowboard leaning up against a stand may accidentally fall down due to wind or other factor and then slide down the ski slope.
- In view of the problems associated with preventing such snowboard sliding, the present invention was devised to solve such problems, it being an object thereof to improve a highback rearward-tiltable-type binding such as Patent Document 1 and thereby provide a snowboard binding in which the stopper function operates in cooperation with the action of removing a boot in the same manner as a ski stopper, and a stopper device for a snowboard binding that demonstrates the stopper function by being attached to the binding of a highback rearward-tiltable-type binding.

FIG. 8 is a view illustrating the operation of the lock lever of example 5. - Preferred embodiments of the present invention are briefly described below with reference to the diagrams while indicating the effects of the present invention.
- The snowboard binding A of the present invention (first aspect) has a
highback 4 in the rear part of abase section 3 that is rotatably and pivotably mounted in the longitudinal direction, and thehighback 4 is locked in a state in which rearward rotation is impossible by alock mechanism 6 while aboot 2 is worn. - Specifically, a
lock lever 7 rotatably provided to the rear surface section of thehighback 4 is rotatably operated, and when thelock lever 7 is extended along the rear surface section of thehighback 4, a connectingcord 8 provided so as to span between thelock lever 7 and thebase section 3 is tensioned, thehighback 4 is placed in a locked state in which rearward rotation is impossible, and theboot 2 placed on thebase section 3 is bound to thebase section 3 by thehighback 4 and astrap 5 provided in a more front-side position of thebase section 3 than the highback 4 (resulting in a state in which theboot 2 is worn. - When the
boot 2 is to be removed from the binding A, thelock mechanism 6 is unlocked and rotated so as to tilt thehighback 4 rearward. - Specifically, when the
lock lever 7 extended along the rear surface section of the highback 4 (maintaining the locked state) is rotatably operated so as to be caused to project rearward from the rear surface section of thehighback 4, the connectingcord 8 slackens and thehighback 4 is placed in an unlocked state in which rearward rotation is possible. - The
highback 4, when placed in an unlocked state, automatically rotates rearward by the rotatable urging of anurging body 9 provided to thehighback 4, and when thehighback 4 automatically rotates rearward, and so that when thehighback 4 arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, the connectingcord 8 is tensioned, the projecting orientation of thelock lever 7 from thehighback 4 rear surface section is maintained, and thelock lever 7 in the projecting orientation makes contact with the snow surface S below the snowboard 1 to bring about a slide-preventing effect. - Therefore, when the
lock lever 7 is rotatably operated to the unlocked state in order to remove theboot 2, an effect for preventing the snowboard 1 from sliding brought about by thelock lever 7 is automatically demonstrated. Accordingly, the process for winding a bothersome tether about the leg is not required, and there is no poor appearance of the tether winding. - When the
highback 4 is rotated rearward, theboot 2 is allowed to move rearward in relation to thebase section 3, and theboot 2 is allowed to move to the rearward position unrestrained by thestrap 5, whereby theboot 2 can be removed from thebase section 3. - Therefore, the
boot 2 can be mounted to or dismounted from thebase section 3 without removing thestrap 5, and once the state of restraint of the boot by thestrap 5 has been adjusted, the same state of restraint of theboot 2 can be created each usage without the process for adjustment each time theboot 2 is mounted/dismounted. - When the
boot 2 is to be remounted, theboot 2 is placed on thebase section 3, and thehighback 4 is rotated forward against the urging force of theurging body 9 and brought into line with the rear section of theboot 2 to produce the locked state. Therefore, thelock lever 7 can be separated from the snow surface S and the slide-preventing state released. - In other words, a slide-preventing effect is demonstrated while the
boot 2 is being removed from the binding A in similar fashion to a ski stopper, and it is therefore possible to prevent the snowboard 1 from sliding down the ski slope without a tether attachment, to prevent the snowboard 1 from sliding down the ski slope when theboots 2 are mounted or dismounted (when both feet are removed from the binding), and to prevent a snowboard 1 leaning up against a stand from accidentally falling down due to wind or other factor and then slide down the ski slope. It is thereby possible to avoid accidents in which an uncontrolled snowboard 1 collides with other skiers and snowboarders. - With the stopper device for a snowboard binding of the present invention (sixth aspect), an
urging body 9 can be attached to thehighback 4 in a well-known snowboard binding A comprising abase section 3 attached to a snowboard 1 and on which aboot 2 can be mounted, ahighback 4 pivotably mounted on a rear part of thebase section 3 and capable of rotating in the longitudinal direction with respect to thebase section 3, astrap 5 provided in a more front-side position of thebase section 3 than thehighback 4, and anunlockable lock mechanism 6 for locking thehighback 4 in a state in which rearward rotation is impossible, the lock mechanism having alock lever 7 rotatably provided to a rear surface section of thehighback 4 and a connectingcord 8 provided so as to span between thelock lever 7 and thebase section 3, and being configured so that when thelock lever 7 is extended along the rear surface section of thehighback 4 by a rotating operation, the connectingcord 8 is tensioned and thehighback 4 is placed in a locked state in which rearward rotation is impossible, and so that when thelock lever 7 in the locked state is caused to project rearward from the rear surface section of thehighback 4 by therotation operation 4, the connectingcord 8 slackens and thehighback 4 is placed in an unlocked state in which rearward rotation is possible. - At this point, the same effect as the snowboard binding A of the first aspect described above can be demonstrated by the rotatable urging of the
highback 4 imparted by theurging body 9. - Specific examples of the present invention are described below with reference to the
FIGS. 1 to 5 . - The present example is applied to a binding A for mounting a front foot of a left and right pair of snowboard bindings.
- As shown in
FIGS. 1 to 3 , the binding A uses a well-known rearward-tiltable type highback 4 (a type in which thehighback 4 is tilted rearward to allow theboot 2 to be dismounted from the base section 3) composed of abase section 3 attached to the upper surface of a snowboard 1 and on which theboot 2 can be mounted, ahighback 4 pivotably mounted on a rear part of thebase section 3 and capable of rotating in the longitudinal direction with respect to thebase section 3, astrap 5 provided in a more front-side position of thebase section 3 than thehighback 4, and anunlockable lock mechanism 6 for locking thehighback 4 in a state in which rearward rotation is impossible. - More specifically, the
base section 3 has anattachment wall section 13 erectly disposed on both the left and right sides as shown inFIGS. 2 and 3 , the lower part on both sides of thehighback 4 are rotatably and pivotably mounted on the rear end section of theattachment wall section 13 to thereby allow pivoting in the longitudinal direction with respect to thebase section 3 between a state in which at least thehighback 4 has been tilted forward to thebase section 3 and a state in which the highback has been tilted to a near horizontal orientation rearward to the base section 3 (seeFIG. 5 ), and the state shown inFIG. 5 is the rearward-rotation-limit position of thehighback 4. - An
ankle strap 5A serving as thestrap 5 of theattachment wall section 13 is rotatably and pivotably mounted in a position below a pivot-mounting section 14 of thehighback 4, atoe strap 5B used as thestrap 5 is rotatably and pivotably mounted on the front end part of theattachment wall section 13, and a shell portion of theboot 2 is furthermore pressed into theankle strap 5A and thetoe strap 5B and a pressingmember 15 for restraining is provided in a spanned state. - A
ratchet mechanism 16 is provided to theankle strap 5A as well as thetoe strap 5B, and the degree of pressing (degree of fastening) on theboot 2 by the pressingmember 15 can be adjusted. - The
lock mechanism 6 has alock lever 7 rotatably provided to the rear surface section of thehighback 4, and a connectingcord 8 provided so as to span between thelock lever 7 and thebase section 3. - The
lock lever 7 is formed in a strip shape, the tip part thereof being atip operation part 11, and the base end part being rotatably and pivotably mounted betweenattachment pieces 18 protruding rearward in left and right positions in about the center of the rear surface section of thehighback 4. - The
lock lever 7 has a through-hole 19, through which awire 8 used as theconnection cord 8 is inserted, formed between the facing side surfaces of the lock lever, and both ends of thewire 8 inserted through the through-hole 19 are secured in a position between the pivot-mounting section of theankle strap 5A and the pivot-mounting section of thetoe strap 5B of theattachment wall section 13. - When the
highback 4 has been brought substantially upright with respect tobase section 3 and thelock lever 7 is rotatably operated and thereby made to extend along the rear surface section of thehighback 4, thewire 8 is tensioned and thehighback 4 is placed in a locked state incapable of rearward rotation, as shown inFIG. 2 . When thelock lever 7 is rotatably operated in this locked state and thereby erected rearward from the rear surface section of thehighback 4, thewire 8 loosened, as indicated by the two-dot-dash line inFIG. 2 , and thehighback 4 enters an unlocked state that allows rearward rotation.Reference numeral 21 in the drawing is a tension-adjusting screw of thewire 8. - An
engagement projection 20 is provided to the base end section of thelock lever 7 as well as to the rear surface section of thehighback 4 between theattachment pieces 18, and when thelock lever 7 is extended along the rear surface section of the highback 4 (when placed in a locked state), theengagement projection 20 on thehighback 4 side rides over theengagement projection 20 on thelock lever 7 side and the locked state is maintained. Also, applying force to rotatably operate thelock lever 7 rearward from the locked state causes theengagement projection 20 on thelock lever 7 side to ride over theengagement projection 20 on thehighback 4 side and produce an unlocked state. - The present example is configured such that, in the known snowboard binding A described above, a
pin 10 serving as the lever-holdingbody 10 is provided so as to span between the left andright attachment pieces 18 further downward than the pivot-mountingsection 17 of thelock lever 7, and when thelock lever 7 rotated rearward from the rear surface section of thehighback 4 makes contact with thepin 10, thelock lever 7 has an orientation erected rearward from the rear surface section of thehighback 4 and is restricted from rotating further downward. - In other words, the
lock lever 7 of the present example is capable of rotatably moving between a position extended along the rear surface section of thehighback 4 and a position in contact with thepin 10 and erect with respect to the rear surface section of the highback 4 (seeFIGS. 2 and 4 ). - When the
highback 4 arrives at the rearward-rotation-limit position from near the rearward-rotation-limit position (arrives in at an orientation nearly horizontal), thelock lever 7 held by thepin 10 in an orientation of projecting from the rear surface section of thehighback 4 is configured so that thetip operation part 11 protrudes downward (is suspended down) from the rear surface section of thehighback 4 which has become horizontal (seeFIG. 5 ). - In the present example, an urging
body 9 for rotatably urging thehighback 4 rearward is provided to thehighback 4, and when thelock lever 7 of thelock mechanism 6 is placed in an unlocked state by the rotatable urging of the urgingbody 9, thehighback 4 automatically rotates rearward. - Specifically, the urging
body 9 is acoil spring 9A having tensile elasticity, and thecoil spring 9A is provided so as to span between thehighback 4 and thebase section 3. - The
coil spring 9A is provided with anattachment ring 12 serving as theattachment section 12 at both end parts thereof, a machine screw or the like is inserted through theattachment ring 12 to attach one end of thecoil spring 9A in a position near the lower part of the rear surface section of thehighback 4, and the other end of thecoil spring 9A is attached to a position near the rear part of the side surface section of thebase section 3. - Two
coil springs 9A are provided, one between the left side surface section of thebase section 3 and the left side position of the rear surface section of thehighback 4, and one between the right side surface section of thebase section 3 and the right side position of the rear surface section of thehighback 4. Thecoil spring 9A elongates when thehighback 4 has become substantially upright in relation to thebase section 3, and has a length dimension that generates a return urging force. When thelock lever 7 of thelock mechanism 6 is placed in an unlocked state, the rotational urging force of thecoil spring 9A immediately acts on thehighback 4 and thehighback 4 automatically rotates rearward. - When the
highback 4 arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position due to the rotational urging of the urging body 9 (coil spring 9A), the connecting cord 8 (wire 8) is tensioned, the orientation of thelock lever 7 projecting from the rear surface section of thehighback 4 is held in place, and thelock lever 7 in the projecting orientation protrudes downward from the rear surface section of thehighback 4, which has become substantially horizontal. - The
lock lever 7 of the present example is further described below. When thehighback 4 has arrived at the rearward-rotation-limit position or near the rearward-rotation-limit position due to the rotational urging of thecoil spring 9A and thelock lever 7 has protruded downward, the lock lever assumes the form of a band plate of such length that thetip operation part 11 protrudes downward further below the lower surface of the snowboard 1 (seeFIG. 5 ). In other words, thelock lever 7 makes contact with the snow surface S so as to pierce the snow surface S below the snowboard 1, and thereby demonstrates the effect of preventing the snowboard 1 (snowboard binding A) from sliding along the snow surface S. - Therefore, in accordance with the present example configured in the manner described above, when the
lock lever 7 is rotatably operated to the unlocked state in order to remove the front foot (boot 2), thehighback 4 automatically rotates rearward and thelock lever 7 makes contact with (pierces) the snow surface S, and effect of preventing the snowboard 1 from sliding is demonstrated. - When the front foot (boot 2) is to be mounted again, the
boot 2 is placed on thebase section 3, thehighback 4 is thereafter rotatably operated forward against the urging force of the urgingbody 9 and made to line up with the rear section of theboot 2. Thelock lever 7 is rotatably operated and set in a locked state, and thelock lever 7 is therefore separated from the snow surface S and the slide-preventing state is released. - The binding A of the present embodiment can also be used as a binding for mounting the rear foot, but in such a case, the slide-preventing effect is demonstrated when the rear foot is removed from the binding in order to perform a skating action. Therefore, the binding is used for mounting the front foot.
- Example 2 of the present invention is described in detail below.
- The present example is a case of a stopper device for a snowboard binding capable of being attached (retrofitted) to the known binding A described in detail in example 1. Specifically, the configuration is provided with the urging body 9 (
coil spring 9A) and the lever-holding body 10 (pin 10) shown in example 1. - When the urging
body 9 and the lever-holdingbody 10 are attached to thehighback 4, thehighback 4 automatically rotates rearward by the urging force of the urgingbody 9 when thelock lever 7 of thelock mechanism 6 has been placed in an unlocked state. When thehighback 4 arrives at the rearward-rotation-limit position or near the rearward-rotation-limit position, the projecting orientation of thelock lever 7 from the rear surface section of thehighback 4 is held by the tension of the connectingcord 8 and the orientation holding effect of the lever-holding body (pin 10), and thelock lever 7 in the projecting orientation makes contact with the snow surface S below the snowboard 1 and demonstrates a slide-preventing effect. - The urging
body 9 and the lever-holdingbody 10 can be attached to the binding A using the same process as example 1 by, e.g., the user or a professionally skilled practitioner. - The details of the present example are repetitions of the description of example 1 and are therefore omitted. Also, a retrofitting device that uses configurations of examples 3 to 5 below may also be used.
- In the case of a retrofitting device such as the present example, a replacement lever having sufficiently length to replace the
lock lever 7 can be provided as a countermeasure to the case in which the length of thelock lever 7 is insufficient for demonstrating a slide-preventing effect on the snow surface S. Alternatively a lever attachment that can be mounted on thelock lever 7 may be provided. - Example 3 of the present invention is described in detail below with reference to
FIG. 6 . - The present example is a case in which a
coil spring 9A serving as the urgingbody 9 in example 1 also spans between the center position near the lower part of the rear surface section of thehighback 4 and the center portion of the rear section of thebase section 3, and thehighback 4 is rotatably urged rearward by threecoil springs 9A. - A
single coil spring 9A serving as the urgingbody 9 may be provided so as to span between thehighback 4 and thebase section 3, or four or more coil springs may be provided in the spanned state. - The configuration is otherwise the same as example 1.
- Example 4 of the present invention is described in detail below with reference to
FIG. 7 . - The present example is a case in which the configuration of the urging
body 9 is different from that in example 1. - Specifically, the urging
body 9 of the present example is atorsion spring 9B. - More specifically, the
torsion spring 9B is supported about the pivot-mountingsection 14, one end of thetorsion spring 9B interlocks with thehighback 4, the other end interlocks with thebase section 3, and thetorsion spring 9B rotatably urges thehighback 4 rearward. - The
torsion spring 9B may be provided to both the left and right pivot-mountingsections 14, or to only one of the pivot-mountingsections 14. Thetorsion spring 9B may be used in combination with thecoil spring 9A indicated as the urgingbody 9 in example 1. - The configuration is otherwise the same as example 1.
- Example 5 of the present invention is described in detail below with reference to
FIG. 8 . - The present example is a case in which a lever-urging
body 22 for rotatably urging thelock lever 7 rearward to be erected rearward from the rear surface section of thehighback 4 is provided to thelock lever 7 in example 1. - Specifically, the lever-urging
body 22 is atorsion spring 22. Thetorsion spring 22 is supported about the pivot-mountingsection 17. For example, one end of thetorsion spring 22 interlocks with thelock lever 7, the other end interlocks with the rear surface section of thehighback 4 or theattachment piece 18, and thetorsion spring 22 rotatably urges thelock lever 7 rearward. - The lever-urging
body 22 may be another elastic body other than thetorsion spring 22. - The configuration is otherwise the same as example 1.
- The present invention is not limited to examples 1 to 5; the specific configuration of constituent features may be designed, as appropriate.
